How do currents affect climate? What influences wind patterns?<br /><br />Main Idea Drawings (+1)<br />Student Notes (+1)<br />A current is a continuous movement of water that transports materials from one place to another. There are surface currents and deep water currents. Two examples include:<br />1. Ocean currents help ships, animals, and other things move around the globe.<br />2. Surface currents and deep currents: warm waters move and bring warm weather.<br /><br />Surface Currents<br />Surface currents are movements of water flowing horizontally in the upper part of the ocean's surface caused by wind. Surface currents affect the climate by moving warm and cold water around the globe.<br /><br />Cold Currents<br />Denser currents move from the poles towards the equator and sink to the bottom.<br /><br />Warm Currents<br />Warm currents bring less dense water from the equator towards the poles near the surface.<br /><br />Gyre<br />Gyres are huge, rotating current systems dominating the surface waters of the oceans. One or more gyres move in a specific direction.<br /><br />Gyres of the equator move in a clockwise direction, while gyres of the lower half of the earth move in a counterclockwise direction. This is due to the Coriolis Effect, which is caused by the Earth's rotation on its axis. Winds curve to the right (clockwise) in the Northern Hemisphere and to the left (counterclockwise) in the Southern Hemisphere. This effect influences the direction of wind and current patterns.<br /><br />Example of a Surface Current<br />The fastest surface current that keeps ice-free in the winter is called the Gulf Stream.
